Comments on defects in the a(r) Toda field theories

Ed Corrigan, Cristina Zambon

Research output: Contribution to journalArticlepeer-review


A simple, basic, argument is given, based solely on energy-momentum considerations to recover conditions under which a_r affine or conformal Toda field theories can support defects of integrable type. Associated triangle relations are solved to provide expressions for transmission matrices that generalize previously known examples calculated for the sine-Gordon model and the a_2 affine Toda model.
